Which of the substances, the formulas of which are given below, interact with sodium hydroxide: SO3 Cu (OH) 2 Al HCL H2SO4. Write the equations of possible reactions, consider the redox process.
SO3 + 2NaOH = Na2SO4 + H2O
Al + NaOH = NaAlO2 + H2
HCl + NaOH = NaCl + H2O
H2SO4 + 2NaOH = Na2SO4 + 2H2O
Cu (OH) 2-does not react
Answer: SO3, Al, HCL, H2SO4
